2 Guys Ducting is not only an installation company but also a design company. We are trained and certified in the proper software and methodologies to design geothermal and air source heat pump systems in-house using Manuals J, D, and S and proper system design practices.



We are one of the few companies that are certified as both designers and installers. Many companies outsource their designs to third parties. We do not. All design and engineering work is done in-house.


Based in Rochester, NH, we serve projects across New Hampshire, Massachusetts, Maine, and Vermont, scheduling by region to keep timelines efficient and dependable.

Why Choose Geothermal?

Geothermal heating and cooling offers major long-term benefits, including:

  • Lower operating costs and improved efficiency
  • Consistent comfort through New England winters and summers
  • The only heat pump system that does not require fossil fuels or, in many cases, any backup heating at all.
  • Quiet operation and dependable performance
  • Geothermal heat pumps are indoor equipment, and their ground loop "condensers" are in the ground. This results in an extremely long system lifespan compared to fossil fuel and air source heat pump systems, often two to two-and-a-half times longer.

Geothermal Services We Provide

  • Inside: Ground source heat pump systems, both water-to-water and water-to-air
  • Outside: Ground source systems. We install closed-loop and open-loop geothermal applications
  • Complete Manual J, Manual D, and Manual S to assure proper system sizing and design for your project
  • High-efficiency heating and cooling solutions in two-stage and variable-speed equipment
  • Residential and small commercial applications

Experience Matters

Geothermal installation isn’t a “one size fits all” job. It requires knowledge, planning, and proper execution to perform the way it’s designed to. Our team brings decades of hands-on experience and a detail-driven approach to every project—because the best results come from doing it professionally, not doing it fast.
